To all 'whom it may concern.'

Be it known that I, REINHOLD HERMAN, a citizen of the United States of America, residing at Grafton, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Condensers, of which the following is a specification, reference being had therein to the accompanying drawing.

is invention relates to condensers for steam or other fluids and the object thereof is to provide a condenser in the manner as hereinafter set forth whereby the volume of fluid to be condensed will be reduced to a minimum, while at the same time increas ing the area of the cooling surface thereby quickly performing the condensing operation. Although the invention is designed primarily for the condensing of steam or other fluids, yet it is so set up that it can be readily adapted as a cooling apparatus for hot liquids of any character for which the apparatus may be found applicable.

Further objects of the invention are to provide a condenser in the manner as hereinafter set forth and which shall be simple in its construction, strong, durable, efllcient in its operation, readily set up for use, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accom anying drawing, wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifica tions can be resorted to which come within the scope of the claims hereunto appended.

ln describing the invention in detail, reference is hadto the accompanying drawings wherein like reference characters denote corresponding arts through the several views and in which);

Figure 1 is a vertical sectional view of a condenser in accordance with this invention. Fig. 2 is a tions of the steam head, and Fig. 3 is a like view of the other section of the steam head.

A condenser in accordance with this in- .vention comprises a series of steam conducting tubes and a series of water conducting tubes surrounded by a water jacket.

perspective View of one of the sec-` The steam conducting tubes are indicated by the reference character 1 and the water conducting tubes by the reference character 2. The latter extend through the former and said water tubes are of such diameter with respect to the steam tubes as to form contractive passages 3 thereby reducing the volume of steam to a very small minimum, while at the same time providing a cooling surface of large area. The tubes 1 at one end are secured in a plate or sheet 4, openings being provided in the plate 4 to receive tubes 1, plate 4 being furthermore provided with bosses 5 constituting bearings for the tubes. The plate 4 is also formed with a laterally-extendng flange 6, having off-sets 7, the flange 6, abutting against the flange 8, formed upon an outer sheet or plate 9. The flange 8 is formed with off-sets 10, which abut against the off-sets 7. The off-sets of the plates are secured together by the holdfast device 11 and when the plates 4 9 abut and are secured together the steam space 12 is formed, which has an inlet 13 communicating with a steam supply. The plate 9 has secured therein on end of tubes 2, these latter extend across the steam space 12. Openings are provided in the plate 9 to receive the tubes 2. The plate 9 is furthermore provided with bosses 14 to constitute bearings for the tubes 2. The tubes 2 have their ends alternately connected together by the unions 15 and by such arrangement the water is caused to circulate in a sinuous manner.

Communicating with one of the upper tubes 2 is a water supply pipe 16, while one of the lower tubes 2 has connected thereto a discharge pipe 17. A discharge pipe for the condensates is indicated by the reference character 18.

lnclosing the tubes is a jacket 19 having an inlet 20 which communicates with the pipe 16 and further provided with an outlet 21. A sheet or plate 22 is provided for supporting the ends of the tubes 2 opposite to the ends which are supported by the plate 9 and a sheet or plate 23 is provided for supporting the ends of the tube 1 opposite those ends which are supported in the plate 4. The plates 22 and 23 are of a construction similar to the plates 4-9, and the like reference characters are applied thereto. The

plates 22 and 23 form a steam space 24. As the pipes 2 extend through the steam spaces 12 and 24 it is evident that the cooling medium circulating through the pipes 2 will condense the steam within said spaces.

'From the foregoing construction, it is evident that a condenser is set up in which is provided an unusually large cooling surface for the fluid to be condensed, and that furthermore the volume of the fluid to be condensed is reduced to a very small minimum and by such an arrangement, it is evident that the condensing operation is vastly facilitated. Furthermore the steam conducting pipes are not only cooled exteriorly owing to the arrangement of the water jacket surrounding the tubes, but are also cooled internally owing to the circulation of water through the pipes 2. The manner of operating the device can be reversed in this particular, that the water space may be used for steam and the steam space may be used for the water, which in either case will give the same result.

Although the condenser is designed primarily for use for condensing steam, yet it is y evident that it can be employed as a cooling apparatus for hot liquids.

lVhat l claim is 1. A condenser comprising two airs of flanged plates, the flanges of the p ates of each pair abutting against each other and thereby providing a fluid receivingl space, means for securing the plates of each pair together, fluid receiving pipes having their ends connected to the inner plates of each pair of lates and opening at their ends into said fluid receiving spaces, cooling medium conducting pipes extending through said fluid receiving pipes, across said fluid receiving spaces and having their ends connected in the outer plates of said pairs of plates, and means exteriorly of the outer plates of said airs of plates for alternately connecting the uid conducting pipes together, onel of said fluid receiving spaces provided with an inlet and the other of said fluid receiving spaces with an outlet.
